Prey Naïveté And Predator-Prey Interactions Between Pterois Volitans, Pomacentridae, And Tetraodontidae In Two Reefs In The Guna Yala Archipelago, Panama, Jesse Garrett-Larsen

Independent Study Project (ISP) Collection

The invasion of Pterois volitans along the Atlantic coast of the Americas is one of the top marine conservation issues of the century. Prey naïveté has been suggested as a mechanism for the success of P. volitans, but conclusive field observations have not been completed. This study tested for prey naïveté in situ by comparing time spent by Pomacentridae and Tetraodontidae in close proximity to P. volitans and a native predator, Cephalopholis cruentata. Difference in time spent by Pomacentridae and Tetraodontidae in the presence of the two predators was observed. The predators P. volitans and C. cruentata were sequentially observed …

After The Flood: Fish Farming And Climate Change Adaptation In Chitwan, Nepal, Signe Stroming

Independent Study Project (ISP) Collection

Last summer, Nepal’s Terai region experienced some of the worst flooding in recent memory. Climate change is expected to increase the number of natural disasters that Nepal experiences in coming years, and more vulnerable demographics will be more adversely affected. Fish farming is a highly profitable and slowly growing industry based primarily in the Terai, that many believe is less vulnerable to climate-related risks than conventional forms of agriculture, and thus a possible livelihood adaptation strategy. In this study, I conducted semi-structured interviews with ten farmers in Madi, Chitwan, to understand the daily challenges and threats to fish farming, the …

An Unparalleled Opportunity For An Important Ecological Study, L. David Mech, Shannon M. Barber-Meyer, Juan Carlos Blanco, Luigi Boitani, Ludwig Carbyn, Glenn Delgiudice, Steven H. Fritts, Djuro Huber, Olof Liberg, Brent Patterson, Richard R. Thiel

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Wolves (Canis lupus) and moose (Alces americanus) have been studied since 1958 on 540-squarekilometer Isle Royale National Park, in Lake Superior. Wolves arrived there across the ice around 1949, and the population once increased to about 50, averaging about 25 annually (Mech 1966, Jordan et al. 1967, Vucetich and Peterson 2009). However, for various reasons, wolf numbers there have now dwindled to 2 nonbreeders, and the US National Park Service has proposed reintroducing 20–30 wolves over 3 years (National Park Service 2016). This situation offers an unparalleled opportunity to promote science-based management of this unique national park. …

The Richness And Relative Abundance Of Small Mammals In Old Surface Coal-Mined Sites In Crawford And Cherokee Counties, Kansas, Fabio Giacomelli

Electronic Theses & Dissertations

Species richness and relative abundance (RA) of the small terrestrial mammals were accessed in 20 different unreclaimed old coal mined sites in Crawford and Cherokee counties, southeast Kansas in 2014. Lines of Victor™ wooden snap-traps were set in three habitat types in each area: grassy, brushy and forested during 3-days period in each of the four seasons.

Southeast Kansas was heavily surface-mined (strip-mined) between the 1930’s and the 1970’s and many of these sites were not reclaimed (restored to the appearance of its original landscape). This has resulted in many types of altered habitats in this region such as strip-pits …

Neosho Smallmouth Bass Movement, Spawning, And Associated Environmental Conditions In A Seasonally Discontinuous Stream: The Illinois Bayou, Arkansas, Jacob Herbert Martin

Theses and Dissertations from 2017

The Neosho Smallmouth Bass Micropterus dolomieu velox is a top predator and popular sportfish in Arkansas’ Boston Mountain streams. In this ecoregion, Smallmouth Bass are common in headwater streams that are prone to drying during the summer months. My objectives were to characterize longitudinal movements of adult Smallmouth Bass and to determine the timing of spawning events along with associated environmental variables during the likely spawning months of June and July. Thirty Smallmouth Bass were captured and implanted with radio transmitters in March, and tracked weekly in the Middle Fork of Illinois Bayou until August 2016. Age-0 Smallmouth Bass were …

Humans As Prey: Coping With Large Carnivore Attacks Using A Predator-Prey Interaction Perspective, Vincenzo Penteriani, Giulia Bombieri, José María Fedriani, José Vicente López-Bao, Pedro José Garrote, Luca Francesco Russo, María Del Mar Delgado

Human–Wildlife Interactions

The number of attacks on humans by large carnivores in North America is increasing. A better understanding the factors triggering such attacks is critical to mitigating the risk of future encounters in landscape where humans and large carnivore co-exist. Since 1955, of the 632 attacks on humans by large carnivores, 106 (17%) involved predation. We draw on concepts and empirical evidence from the Predator-Prey Interaction Theory to provide insights into how to reduce predatory attacks and, thus, improve human-large carnivore co-existence. Because large carnivore-caused mortality risks for humans are comparable to those shown by other mammal species in response to …

Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas

Human–Wildlife Interactions

Human–primate conflicts in Africa have been increasing due to increased human population growth and the resulting competition for forest resources. The Ethiopian Highlands in northern Ethiopia, home to the grivet monkey (Chlorocebus aethiops), once consisted of large forested areas. This region has been severely denuded and now exhibits only small forest patches remaining at sites with special cultural significance in the immediate vicinity of churches. These forest patches, surrounded by agricultural crops, provide refugia habitat for the grivet monkey. We randomly surveyed 50 villagers living near the Batiero Church Forest, a 45-ha forest patch located in northern Ethiopia, to determine …

Substrate-Borne Communication In Chameleons: Do Vibrations Induce Behavioral Changes?, Emily J. Hamilton

Mahurin Honors College Capstone Experience/Thesis Projects

Understanding the modes of communication used by a species is essential to understanding their ecology, behavior, and evolution. Substrate-borne vibrations have been reported to be produced by the veiled chameleon (Chamaeleo calyptratus), possibly implemented by use of a gular pouch. We found that veiled chameleons produced vibrations under dominance and mating behavioral contexts. We tested the sensitivity of veiled chameleons to vibrations by placing chameleons, one at a time, on a wooden dowel attached to a permanent magnetic shaker and recording each chameleon’s behavior before, during, and after a three-pulse vibrational stimulus of 25, 50, 150, 300, or 600 Hz. …

Ecosystem Biomonitoring With Edna: Metabarcoding Across The Tree Of Life In A Tropical Marine Environment, Michael Stat, Megan J. Huggett, Rachele Bernasconi, Joseph D. Dibattista, Tina Berry, Stephen J. Newman, Euan S. Harvey, Michael Bunce

Fisheries Research Articles

Effective marine management requires comprehensive data on the status of marine biodiversity. However, efficient methods that can document biodiversity in our oceans are currently lacking. Environmental DNA (eDNA) sourced from seawater offers a new avenue for investigating the biota in marine ecosystems. Here, we investigated the potential of eDNA to inform on the breadth of biodiversity present in a tropical marine environment. Directly sequencing eDNA from seawater using a shotgun approach resulted in only 0.34% of 22.3 million reads assigning to eukaryotes, highlighting the inefficiency of this method for assessing eukaryotic diversity. In contrast, using ‘tree of life’ (ToL) metabarcoding …

Physiological Ecology Of Four Endemic Alabama Species And The Exotic Asiatic Weatherfish, Misgurnus Anguillicaudatus (Cantor, 1842), Lindsay M. White, Mark E. Meade, Benjamin A. Staton

Southeastern Fishes Council Proceedings

The occurrence of Asiatic Weatherfish, Misgurnus anguillicaudatus, in Alabama, a state known for its rich biodiversity, has generated concern among conservation managers. The current study used respirometry techniques to investigate the effects of increasing temperature on four native southeastern fishes (one cyprinid, two percids, and one elassomid) and the non-native M. anguillicaudatus. A minimum of five individuals of each species were used, and three experimental temperatures were chosen to represent spring and summer averages of northeast Alabama streams (15, 20, and 25°C). Overall, mean standard metabolic rates (SMRs) for M. anguillicaudatus were low (97.01, 127.75, and 158.50 mg …

The Inconvenient Truth About Thinking Chickens, Lori Marino

Animal Sentience

Original Abstract: Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. Some birds are now known to be on a par with many mammals in their intelligence, emotional sophistication, and social interaction. Yet views of chickens have largely remained unrevised in light of this new evidence. In this paper, I examine the data on cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities with other birds and other vertebrates, particularly …

First Report Of A Population Of Western Blacknose Dace (Rhinichthys Obtusus) In The Brushy Creek System Of The Black Warrior River Drainage, Alabama, Eric Bauer, Malorie M. Hayes

Southeastern Fishes Council Proceedings

Alabama is home to the southernmost populations of Rhinichthys obtusus, the Western Blacknose Dace. Within Alabama, R. obtusus is found in the Tennessee, Coosa, and Black Warrior River basins, but its presence in the Black Warrior River drainage has been limited. Until now, R. obtusus in the Black Warrior drainage has only been reported as collections of 1 to 4 specimens at a time in the Sipsey Fork drainage. Herein, we report two novel occurrences of R. obtusus in the headwaters of the Brushy Creek system in the Black Warrior River drainage including a singleton and a large population. …

Department of Animal Science: Faculty Publications

The objectives of this study were 1) to determine if supplementation of zilpaterol hydrochloride (ZH) altered select organ weights, histology, and cardiac anatomical features at harvest and 2) to determine if administration of a corticotropin-releasing hormone (CRH) and vasopressin (VP) challenge following 20 d of ZH supplementation altered the blood chemistry profile in cattle. Crossbred heifers (n = 20; 556 ± 7 kg BW) were randomized into 2 treatment groups: 1) control (CON), without ZH, and 2) zilpaterol (ZIL; ZH at 8.33 mg/kg [DM basis] for 20 d). On d 20 of supplementation, heifers were fitted with indwelling jugular …

Rehabilitation Of An Injured Golden Eagle (Aquila Chrysaetos): A Case Study, Fida Muhammad Khan, Fakhar-I- Abbas, Abu Ul Hassan Faiz

Journal of Bioresource Management

Habitat destruction and anthropogenic activities cause wild birds to migrate towards urban areas in search of food and sometimes nesting in high-roof buildings, where they are caught by local people using different techniques and are further used for hunting or recreational purposes. An injured Golden Eagle (Aquila chrysaetos) was found entangled in bushes near the vicinity of Balkasar Research Complex, Chakwal, Pakistan. After complete physical examination, a wound on the right wing and closed leg fracture was diagnosed. The successful treatment was done by anti-parasitic and anti-bacterial drugs with careful monitoring. Splint was adjusted after aligning the fractured …

Can Squirrel Monkeys Learn An Abna Grammar? A Re-Evaluation Of Ravignani Et Al. (2013), Stefano Ghirlanda

Publications and Research

Ravignani et al. (2013) habituated squirrel monkeys to sound sequences conforming to an ABnA grammar (nD1;2;3), then tested them for their reactions to novel gram- matical and non-grammatical sequences. Although they conclude that the monkeys ``consistently recognized and generalized the sequence ABnA,'' I remark that this conclusion is not robust. The statistical significance of results depends on specific choices of data analysis, namely dichotomization of the response variable and omission of specific data points. Additionally, there is little evidence of generalization to novel patterns (n D 4;5), which is important to conclude that the monkeys recognized the ABnA grammar beyond …

Prothonotary Warbler Nest Selection, Nest Survival, Demographic Parameters, And Spatial Plumage Color Variation, Morgan Christopher Slevin

Student Theses and Dissertations

(I) To aid conservation efforts for the declining Prothonotary Warbler (Protonotaria citrea), we studied warblers breeding in White River NWR to assess relationships between nest site microhabitat variables and both habitat selection patterns and nest survival; furthermore, we estimated demographic parameters of individuals breeding in natural cavities vs. nest boxes. Prothonotary Warblers preferred nesting in relatively high, shallow cavities in dead trees; however, canopy cover was negatively related to nest survival. Demographic parameters generally did not differ between nest type. (II) To explore how carotenoid-derived coloration and associated signaling vary spatially, we compared warblers breeding in Arkansas and Virginia, USA. …

Pituitary Genomic Expression Profiles Of Steers Are Altered By Grazing Of High Vs. Low Endophyte-Infected Tall Fescue Forages, Qing Li, Raquel Hegge, Phillip J. Bridges, James C. Matthews

Animal and Food Sciences Faculty Publications

Consumption of ergot alkaloid-containing tall fescue grass impairs several metabolic, vascular, growth, and reproductive processes in cattle, collectively producing a clinical condition known as “fescue toxicosis.” Despite the apparent association between pituitary function and these physiological parameters, including depressed serum prolactin; no reports describe the effect of fescue toxicosis on pituitary genomic expression profiles. To identify candidate regulatory mechanisms, we compared the global and selected targeted mRNA expression patterns of pituitaries collected from beef steers that had been randomly assigned to undergo summer-long grazing (89 to 105 d) of a high-toxic endophyte-infected tall fescue pasture (HE; 0.746 μg/g ergot alkaloids; …

Geolocator Data Reveal The Migration Route And Wintering Location Of A Caribbean Martin (Progne Dominicensis), Noah G. Perlut, Thomas C. Klak, Eldar Rakhimberdiev

Environmental Studies Faculty Publications

Caribbean Martins (Progne dominicensis) are common breeders on most Caribbean islands, where they regularly roost and nest in urban areas from February through August. However, from September through January, the basic ecology of this species--its migration and wintering locations--are largely unknown. In 2012, we deployed seven geolocators, and in 2014, we recovered one geolocator from a female Caribbean Martin on the Commonwealth of Dominica, a small eastern Caribbean island. Her wintering location was the western portion of the State of Bahia, Brazil, ~3550 km southeast of Dominica. Although the location of the non-breeding grounds changed minimally, the fall …

Diet And Habitat Analysis Of Barn Owls (Tyto Alba) Nesting At Ponca State Park, Ann Spilker, Joseph A. Gubanyi

Nebraska Bird Review

In 2015 Barn Owls (Tyto alba) nested on the floor of a grain bin in Ponca State Park, Dixon County. Seven nestlings were observed (Figure 1). It is believed that 6 fledged (one carcass was found on the floor of the bin September 26). Barn Owls were not observed the following spring (Jan Johnson, personal communication). Because there are few records of Barn Owls in the region, we collected data to better understand the Barn Owl nesting in Ponca State Park. Barn Owl prey and their importance to reproductive success has been well documented (Marti et al. 2005; Gubanyi et …

Changes in breeding ranges and numbers of Nebraska breeding birds are the primary focus of a Summer Seasonal Report. Every year there are changes to be noted; this year is no exception. Although most of the phenomena listed below are examples of dispersing individuals without breeding evidence, these often indicate breeding range expansion. White-winged Doves are becoming numerous in southern and western Nebraska, although breeding in far eastern Nebraska was only the 5th report for the state. Chuckwill’s- widow continues to creep westward in the south; the westernmost report to date was of one that crossed the 100-mile gap from …

Impact Of Socioeconomic Factors On Florida Consumers' Perceptions On Use Of Chemical In Locally Or Regionally Produced Livestock Products, David Nii O. Tackie, Akua Adu-Gyamfi, Janette R. Bartlett, Bridget J. Perry

Professional Agricultural Workers Journal

Abstract

The use of chemicals in livestock production has been an issue for consumers for several decades. This study, therefore, assessed the impact of socioeconomic factors on Florida consumers’ perceptions on the use of chemicals in locally or regionally produced livestock products. Data were collected from a sample of 404 participants from several Florida counties and were analyzed using descriptive statistics and ordinal logistic analysis. Most of the respondents were of the opinion that using chemicals in locally or regionally produced and sold beef or goat meat was a serious or somewhat serious hazard. The ordinal logistic regression results showed …

Studying The Mechanisms Of Developmental Vocal Learning And Adult Vocal Performance In Zebra Finches Through Lentiviral Injection, Zhimin Shi, Ofer Tchernichovski, Xiaoching Li

Publications and Research

Here we provide a detailed step-by-step protocol for using lentivirus to manipulate miRNA expression in Area X of juvenile zebra finches and for analyzing the consequences on song learning and song performance. This protocol has four parts: 1) making the lentiviral construct to overexpress miRNA miR-9; 2) packaging the lentiviral vector; 3) stereotaxic injection of the lentivirus into Area X of juvenile zebra finches; 4) analysis of song learning and song performance in juvenile and adult zebra finches. These methods complement the methods employed in recent works that showed changing FoxP2 gene expression in Area X with lentivirus or adeno-associated …

Preventing Horse-Related Injuries By Watching Out For Other Humans, William R. Gombeski Jr., Fernanda C. Camargo, Holly Wiemers, Connie Jehlik, Polly Haselton Barger, James Mead

Animal and Food Sciences Faculty Publications

The more one rides or handles horses, the more likely one is to have a horse-related injury. These injuries are caused by many factors, including those generated by other riders, handlers or spectators. An analysis of 266 cases of injured equestrians showed that 16% of those injuries were caused by other humans. A panel of horse riding safety experts felt 63% were preventable, and the injured individuals themselves felt 51% were preventable. The study findings suggest that increased awareness of the role others play in causing horse-related injuries and increased education about common people-caused injuries could reduce the number of …

European Starlings, H. Jeffrey Homan, Ron J. Johnson, James R. Thiele, George M. Linz

Wildlife Damage Management Technical Series

European starlings (Sturnus vulgaris, Figure 1) are an invasive species in the United States. The first recorded release of the birds was in 1890 in New York City’s Central Park. Because starlings easily adapt to a variety of habitats, nest sites and food sources, the birds spread quickly across the country. Today, there are about 150 million starlings in North America. Conflicts between people and starlings occur mostly in agricultural settings. Conflicts can occur during winter in urban and suburban environments, especially in business districts.

Starlings damage apples, blueberries, cherries, figs, grapes, peaches, and strawberries. Besides causing direct losses from …

Veterinary Science Faculty Publications

Many life-cycle processes in parasites are regulated by protein phosphorylation. Hence, disruption of essential protein kinase function has been explored for therapy of parasitic diseases. However, the difficulty of inhibiting parasite protein kinases to the exclusion of host orthologues poses a practical challenge. A possible path around this difficulty is the use of bumped kinase inhibitors for targeting calcium dependent protein kinases that contain atypically small gatekeeper residues and are crucial for pathogenic apicomplexan parasites’ survival and proliferation. In this review, we review efficacy against the kinase target, the parasite growth in vitro, and in animal infection models, as well …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …
